Deus Ex Beta Direct3D Patch 

This beta patch improves performance on most Direct3D cards. 

To install, copy the D3DDrv.dll file to the "System" folder inside your Deus Ex folder (C:\DeusEx\System by default). 

This patch will fix texture thrashing problems (which cause abnormally low framerates) on nVidia and Matrox cards and some z-buffering errors on Matrox cards. 

This is version 1.6.2 of the driver. 

If you wish to go back to the original .dll file provided withthe game, copy the D3DDrv.dll file from the "System" folder on the game CD, to the DeusEx\System folder on your hard drive.
